Rev. James Brownlee/Lavinia McClung Graham

Looking for information on James' parents. He was born in County Down, Ireland, 12 March 1812 and came to the U.S. at the age of 19. He married Lavinia 28 April 1839 in Floyd County, Indiana. His five children were Mary Jane, Harriett Newell, Anna Maria, Addison McClung, and James Henry. I have lots of information on Addison and James Henry but none on the ladies.Rev. James was raised by his grandfather but I have no idea who his parents are.I also have no information on Lavinia.Any help would be greatly appreciated.
